Regulated deficit irrigation (RDI) had been widely used to control amount of
irrigation water supplied to the plant. RDI help plant in arid area to survive and
produce the quality and high yield. A proposed study of the effect of RDI on
growth and phytochemical od Ortosiphon aristatus. 4 levels of treatment will
be imposed which are the no reduction of irrigation water supply (100%), low
reduction of irrigation water (25%), medium reduction of irrigation water
supply (50%) and high reduction of irrigation water (75%). The parameter that
will be evaluated are the height of the plant, leaf area, soil moisture content,
water use efficiency (WUE), stomatal conductor and chlorophyll content of the
leaf. The parameter will be analyze once every week until harvest in
approximately 10 weeks. The growth and phytochemical of the Ortosiphon
aristatus is expected to be higher by the reduction of 75% water (high).
